tmospheric pressure micro-plasmas allow cost-effective
area-selective surface modifications and chemical
functionalization. Plasma patterning technologies are used
in combination with inkjet printing or fluid dispensing and
can be implemented in biosensor and tissue engineering
applications. InnoPhysics has developed and commercializes
the μPlasmaPrint technology, which utilizes a multineedle-to-
plate dielectric barrier micro-discharge at atmospheric pressure
and enables area-selective functionalization by means of a dot-
wise patterning of the plasma treatment/deposition with a
resolution frommillimeters down to 150 μm.
Recently InnoPhysics hasmade significant changes on hardware
and process options in order to enhance the μPlasmaPrint
resolution and to improve the processing and substrates
flexibility. Latest developments will be shown related to
process characterization through surface wettability mapping,
in-situ monitoring of the plasma energy for improved process
feedback and the development of a stand-alone μPlasmaPrint
head with integrated electrode to enable the application of
μPlasmaPrint not only on 2D, flat substrates, but also more
complex, 3D workpieces. On the process side, developments
will be presented to enable non-fouling hydrophilic coatings
in plastic biomedical devices by combining μPlasmaPrint with
liquid coating dispensing. Furthermore recent developments
which enable selective chemistry to obtain patterns of
chemically functionalized substrates as an alternative to direct
μPlasmaPrint deposition will be shown. Examples will involve a
direct, patternedplasmaALD-like approach toobtainmicroscale
patterns of In
